Final answer:
True, measurement error can be minimized but not entirely eliminated; larger sample sizes and skilled measurements enhance reliability and accuracy.
Step-by-step explanation:
It is true that it is hard, but not impossible, to eliminate measurement error in our selection measures. Measurement errors can occur due to various factors such as limitations of the measuring device, the skill of the person making the measurement, and the sample size used. To enhance the accuracy and reliability of measurements, it is important to use high-quality measuring tools, employ skilled personnel, and ensure appropriate sample sizes are taken.
When considering experiments, it is not false that experiments cannot be performed on humans; ethical experiments on humans are conducted in various fields, including medicine and psychology, under strict ethical guidelines. Additionally, larger sample sizes are generally preferred as they tend to reduce chance error and produce more representative results, lowering uncertainty in measurements.
